Something may have already been posted on here about this , but I’ll post it anyway. It would be a good idea to store extra rat poison and some insecticides. If you have power loses and such for extended periods of time , there will be tons of rotting food, drawing flies , rats etc. They will hunt out food and warmth. Just thought I’d add this. Also in flood areas rats along with other vermin will seek higher ground, ants,roaches and spiders aswell.
